An insurance company evaluates many numerical variables about a person before deciding on an appropriate rate for automobile insurance. A representative from a local insurance agency selected a random sample of insured drivers and recorded, X, the number of claims each made in the last three years, with the following results.
X f
1 10
2 20
3 15
4 4
5 3
How many claims are represented in the sample?
126
50
111
118
The total number of claims represented in the sample can be calculated as:
1(10) + 2(20) + 3(15) + 4(4) + 5(3) = 10 + 40 + 45 + 16 + 15 = 126
Therefore, a total of 126 claims are represented in the sample. The correct answer is:
126
